Hi,
Background:
2 sites with vBlocks and using vPLEX for stretched storage with vMSC as well and a stretched layer 2.
Replacing the existing network with NSX which is a good fit here with layer 2 DCI over VXLAN
Keep existing vMSC and not using Cross-VC with NSX.
I have read the design guide but have more question now that before I read it J page 13 -15 and 125 -129

From the design guide, and what i understand, it seems I should have a couple of options but please correct me where i am wrong in my lists below.
- Active/passive ESG with single site used for all egress (no universal objects)
- Dynamic routing with single control VM
- Logical networks stretched across 2 sites
- Active/passive ESG with single site used for all egress (with universal objects)
- UDLR with status = deployed
- Local egress
- ESGS with ECMP northbound
- Logical networks stretched across 2 sites
- Not really worth it since only a single
- Active/Active ESGs with site specific egress (with universal objects)
- no universal control VM – only static routing
- Logical networks stretched across 2 sites
- UDLR with status = Active
For all these options, if you I want to use stateful services:
- Install single ESG with HA enable for active/standby per site.
- Replicate the stateful services manually across sites.
My questions which i hope somebody can help me with:
- How do I configure multiple active ESGs?
- How do I set the ESGs to be either active or passive?
- I would assume you treat these just as physical routers with different GW IP address, is this correct?
- For any of these options, are there any manual intervention required for site failover?
- I know that HA is supported for vCenter, NSX Manager and NSX Controllers.
- What if I have all active ESG’s setup at both sites, will that be an automatic failover?
- With active/passive ESGs we can perform dynamic routing, is that a correct statement?
- Could we use OSPF or BGP?
Thank you
